What is Texel1 in combine mode?

[Rice]

A lot of combine modes are using both Texel0 and Texel1, where Texel1 is coming from?

Ok, from my experience:

the Texture command (from gSPTexture) sets the tile descriptor # to use as Texel 0, and then that # plus 1 is Texel 1 (unless mipmapping i think, but i haven't handled this yet) Is this what you're asking for?

Hmm... I always though RENDERTILE (0) on settile was ALWAYS T0, and T1 was 1. Furthur more, MIP-MAPPING uses TILES 0-6 starting with the value from gSPTexture. That is just my understanding. <enter disclaimer here>

[Dave2001]

Nah, tile descriptor 0 is not always t0. In Banjo Kazooie (if i remember correctly) it wanted to use the third descriptor for t0 on some things.

Good thing to keep in mind as I progress furthur. Thx for the tip. I will check it out. So far, I haven't seen it behave like this.
